Abstract (English): The Problem Based Learning (PBL) learning model is an approach that can be used to improve student learning outcomes. This research aims to find out whether the application of the PBL learning model can improve the mathematical problem solving abilities of students in class VIII-2 at SMP Negeri 8 Medan on rank number material. This research uses a classroom action research method which is carried out in two cycles, with each cycle consisting of two meetings. The research subjects were 30 students in class VIII-2 at SMP Negeri 8 Medan, while the object of the research was increasing students' mathematical problem solving abilities through the application of the PBL learning model to the rank material for the 2024/2025 academic year. Based on data analysis, the average student initial test score was 30.83 with only 3 students achieving completion, while 27 students had not yet achieved completion. After implementing the PBL learning model in cycle I, there was an increase in the average score of the problem solving ability test to 74.83 with 21 students achieving completeness, while 9 students had not yet completed it. In cycle II, there was a further increase with the average score of the students' problem solving ability test being 86.83, with 27 students achieving completeness and 3 students not yet completing it. Student completion in cycle II is in the good category, so it can be concluded that learning has been successful, with more than 85% of students achieving completeness in solving problems. Therefore, it can be concluded that the application of the Problem Based Learning learning model can improve students' mathematical problem solving abilities. [ABSTRACT FROM AUTHOR]
Abstract (Indonesian): Model pembelajaran Problem Based Learning (PBL) merupakan salah satu pendekatan yang dapat digunakan untuk meningkatkan hasil belajar siswa. Penelitian ini bertujuan untuk mengetahui apakah penerapan model pembelajaran PBL dapat meningkatkan kemampuan pemecahan masalah matematis siswa kelas VIII-2 di SMP Negeri 8 Medan pada materi bilangan berpangkat. Penelitian ini menggunakan metode penelitian tindakan kelas yang dilaksanakan dalam dua siklus, dengan setiap siklus terdiri dari dua pertemuan. Subjek penelitian adalah 30 siswa kelas VIII-2 di SMP Negeri 8 Medan, sementara objek penelitian adalah peningkatan kemampuan pemecahan masalah matematis siswa melalui penerapan model pembelajaran PBL pada materi perpangkatan tahun ajaran 2024/2025. Berdasarkan analisis data, rata-rata nilai tes awal siswa adalah 30,83 dengan hanya 3 siswa yang mencapai ketuntasan, sedangkan 27 siswa belum mencapai ketuntasan. Setelah diterapkan model pembelajaran PBL pada siklus I, terjadi peningkatan nilai rata-rata tes kemampuan pemecahan masalah menjadi 74,83 dengan 21 siswa mencapai ketuntasan, sementara 9 siswa belum tuntas. Pada siklus II, terdapat peningkatan lebih lanjut dengan nilai rata-rata tes kemampuan pemecahan masalah siswa menjadi 86,83, dengan 27 siswa mencapai ketuntasan dan 3 siswa belum tuntas. Ketuntasan siswa pada siklus II masuk dalam kategori baik, sehingga dapat disimpulkan bahwa pembelajaran telah berhasil, dengan lebih dari 85% siswa mencapai ketuntasan dalam memecahkan masalah. Oleh karena itu, dapat disimpulkan bahwa penerapan model pembelajaran Problem Based Learning dapat meningkatkan kemampuan pemecahan masalah matematis siswa. [ABSTRACT FROM AUTHOR]
